IN STAL LA TION
UPMAST TRANS CEIVER (DTX-A3)
WARNING
ENSURE THAT ALL POWER SUPPLIES IN THE VICINITY OF THE
TRANSCEIVER ARE ISOLATED BEFORE ANY INSTALLATION TAKES
PLACE.
21 The SharpEye
TM
Upmast Transceiver is supplied in two parts:
(1) Transceiver with Gearbox.
(2) Antenna.
22 The SharpEye
TM
Upmast Transceiver is fitted with a Low Profile Antenna (LPA-A25).
23 The ship’s mounting structure must be capable of withstanding the high starting and
stopping torque generated by the motor fitted in the upmast transceiver.
24 When mounting the upmast transceiver observe the following:
(1) Use the fitting pack supplied with the equipment (refer to Figure 3). The fitting
pack contains fixings that have been tested to withstand the stresses detailed in
paragraph 24.
(2) Recommended tensile strengths and torque loadings for the fixings are stated on
the installation diagram.
(3) For upmast transceivers mounted in excess of 1.8 m above the deck, it is
recommended that a service platform and guard rail are fitted.
(4) Use a suitable jointing compound or sealant to prevent corrosion between the
platform and upmast transceivers/turning mechanism.
CAUTION
The Antenna Window Must NOT Be Painted.
(5) Any chipped or damaged surfaces must be painted with polyurethane paint.
25 With reference to Figures 1, 2 and 3, install the upmast transceiver and antenna following
the procedures below.
26 It is recommended that the antenna is fitted after installing the transceiver/turning
mechanism to avoid damage to the antenna. Only fit the antenna prior to installing the
transceiver/turning mechanism if absolutely necessary, in which case care must be taken to
avoid damage to the antenna when lifting the combined assembly.
